FAQs

Question: What is the primary use of Dijkstra's Algorithm?
Answer: Dijkstra's Algorithm is primarily used to find the shortest path from a source node to all other nodes in a weighted graph.

Question: Can Dijkstra's Algorithm handle negative weight edges?
Answer: No, Dijkstra's Algorithm cannot handle graphs with negative weight edges; it is designed for non-negative weights only.
